Wrong toolbox for the 200x..it should look like this.

This is my 250SX, but the style and connection of the toolbox is the same as the 200X.
Your rear shock may be whipped..or it's a combination of the fact the trike has WAY big rear tires and you're a big guy!!?? My 200X didn't like my large stature..that is why I moved up to the 350X..
